danger. of injury to the-same,--this object bein'gaccomplishedbyproviding a clasp, the gripping or clasplng portion, of which 15 freeof'teeth or other uneven gripp ng surfaces.

Afurtherobject of. rnv invention theprovision of a clasp of a typewherein the.

gripping surfaces are so arranged that the clasp may be used with equalfacility with. both wide and narrow fabrics. I

To the endthat the objects above enu hereinafter pointed out may beattainechl have an improved clasp which in general comprises a pair ofarms preferably of resilient material, one of said arms being providedwith a turned-oven flange extending transversely of the clasp. Thisfiange'when turned over. constitutes an unbroken grippingmembercooperating wlth thei.other arnrof the clasp, so that'when the clasp. isclosed the fabric willbe firmly gripped. I

, I have illustrated several embodiments of my invention in theaccompanying drawingwhereinrp Fig. 1 is a perspective of aclasp-constructed in accordance with my invention,- the clasp being inopen position; y g p Fig. 2 isa side elevation. of-the clasp of Fim, 1,the clasp in. this figure. being in clozed osition; I y Fig. .3 is asection on the line 8-3 of Fig. 2, looking in the direction of thearrows; g Figs. 4 and 5 illustrate a modified form of my improved clasp,Fig. 4-being a side elevation of the same while Fig. 5 is a sectiontaken on the line 55 of Fig. 4;

[10o sam jw'i i The modification of Figs. 4 and comprises arms 6 and 7of'resilie'nt material. These arms are likewise preferably struck from asingle piece of material and are pro-- vided with locking means 8. Theupper arm 6 is provided on its under side with a longitudinallyextending groove 9 which is preferably made by bending the materialalong the line of the groove. The

lower arm 7 is pro i with flange 10 extending longitudinally of the armfor practically the entire length thereof. This flange is benttransversely of the arm and the inner edge thereof is bent upwardly asindicated at 11, so as to form a'resilient gripping edge cooperatingwith the groove 9 already referred to. Here again I provide continuousgripping surfaces, to wit, the groove 9 and and the edge of the flange10 by which fabric may be gripped and securely held.

The clasp of F (3 and 7 comprises an arm 12 similar to the arm 1. of theclasp of Fig. 1, an arm 13 andlocking means 1-1. The arm 13 is providedwith a flange 15 extending substantially the length of the clasp. Thisflange is bent/transversely to the clasp V and then. given a reversebend as indicated at 16. The upper face of the flange is substantiallyflat and lies practically parallel to the under surface of'the arm 12. Ithereby secure good gripping surfaces for receiving the fabric to beclasped, and by giving the flange a reverse bend as described, thegripping action is slightly increased.

In Fig. 8 I have shown a clasp comprising arms 17 and 18 and lockingmeans '19 similar to the arms 1 and2 and the locking The arm 18 isprovided Withaflange 20 extending practically the length of the arm,this flange being bent transversely ofthe arm in the same manner asdescribed in connection with Fig. 1. This flange 20, it will be seen, isprovided with an opening'21, which increases the resiliency of thegripping member and which. enables a heavier material to be employed inthe construction of the clasp than is practicable with the clasp of Fig.1.

Fig. 9 is similar in all respects to the clasp of Fig. 8'with theexception of'the flange thereof. Here I provide arms 22 and 23, lockingmeans 2 1 and a flange 25. This flange is bent transversely of the armand cut out'as indicated at 26, a reinforcing or strengthening rib 2.?being provided to stiffen the flange. This reinforcingmember, it will beunderstood, is an integral part of the flange 25 and is the same as themembers 28 and 29, the flange being cut out at each side of said member27.

It will be seen from the foregoing that I have provided an improvedclasp capable of gripping and securely holding a strip of fabric,whether wide or narrow, Without employing gripping means which areliable to injure the fabric.

It will be seen furthermore that by providing gripping surfacesextending continuously substantially the entire length of the clasp, noparticular care is necessary in applying the clasp to the fabric to begripped.

What I claim is:

1. A clasp comprising a strip of material I folded upon itself to form apair of spacedapart arms, a portion of one of said arms being benttransversely to form an overhanging flange having a floating edge, saidflange extending transversely and longitudinally of the arm, the upperside of saidflange and the under side of the arm above it togetherconstituting cooperating grip ping surfaces.

2; A clasp comprising a pairof arms, a

flange of resilient, material and having a floating edge carried by onearm and coopbeing folded back and transversely of the. arm with which itis integral so that the upper face thereof extends longitudinally of andlies substantially parallel with the under side of the other arm.

4;. A clasp comprising a pair of arms, means for locking said arms toeach other and a flange extending longitudinally of the clasp carried byone of said arms and having a floating edge, said flange being provided,

with an opening therein and being bent in wardly and transversely of theclasp but spaced from, the arm by which it is carried, the upper side ofsaid flange cooperating with the under side of the other arm to-form agripping medium.

5. A clasp comprising two arms one of which has a bent-over portionextending longitudinally' thereof and provided with a floating edge toprovide a resilient flange bent transversely of the clasp and extendingsubstantially the entire length of the clasp.
